中文摘要： 在前人的研究基础上改进了利用热敏电阻测定昆虫过冷却点和体液冰点的装置，经检验其准确度与常用的热电偶法基本相同，但其测定成功率较高，使用方便。本装置先录制热敏电阻值变化的全过程，便于随时调出并准确地读出过冷却点与体液冰点的热敏电阻值；开发了操作方便的昆虫夹，明显缩短了测定时间，提高了测定效率，可用于定期的、连续的昆虫过冷却点与体液冰点的批量测定。
英文摘要： Based on previous studies, improvements to a thermistor designed to test insect super-cooling and humoral freezing points is described. Compared to the normal thermocouple method, the improved device has the same accuracy but a higher test success rate and is more portable. The device first transcribes the thermistor value variation, which makes it easy to call up the super-cooling point and thermistor value at any time. It incorporates an insect clamp which shortens testing time and improves efficiency, and can be used for batch testing insect super-cooling and humoral freezing points both regularly and continuously.
